Whenever I had to go to the bank for whatever reason, I would check out the teller's desks while they were working on my transaction. It passed the time, but it was pretty interesting.

At least at that time, at that bank branch, a typical teller's desk included: 1 Dell desktop and accompanying monitor, 1 automatic bill counter, 1 desk calculator, 1 check reader, probably a few pens and some with cute designs on them, a few stationery holders for various slips, forms, notices and marketing materials.

All in all, pretty boring affair, but near as I can tell banks are basically stuffy offices from the 80s. Just swap out the Dell for I dunno, an IBM PC or an Apple //.
